418 Rev. T. Blackburn on Ilauaiian Neuroptera. 



feel no doubt, however, that species of this family (and pro- 

 bably a good many of them) are strictly endemic. It will 

 readily be believed that an entomologist not making the 

 Neuroptera a specialty would be unlikely to do justice in his 

 collecting to a group of flies so obscure as this ; yet I have 

 three, if not four, distinct species in my scanty collection of 

 Hawaiian Neuroptera. Moreover, I doubt much whether I 

 have seen any of the family very near to any place whither 

 imported plants or shrubs would be taken, and can say quite 

 positively that they are far more numerous at a considerable 

 elevation in the mountain-forests than elsewhere. I have 

 taken Hemerobiidte on Oahu, Maui, and Hawaii, and have a 

 strong impression of having seen them on Kaui, Molokai, and 

 Lanai. 1 shall not attempt to describe any of them, as I 

 have neither literature nor special knowledge of the family 

 sufficient to justify me in doing so. None of them appear to 

 me very remarkable or very different from European forms. 



Chrysopidse. 



This family is richly represented in the Hawaiian archi- 

 jielago, and probably there are scores of distinct species. I 

 think I have met with examples on every island, and in all 

 kinds of localities, often in considerable abundance. 



There are three species in my collection which I shall 

 venture to describe as possessing strongly marked characters 

 not likely to be capable of confusion with those of other 

 species. 



Anomahchrysa Maclachlani, sp. no v. 



Body, legs, palpi, and antennee pale reddish yellow, the 

 hind body being darker towards the apex ; basal joint of 

 antennas strongly bulbose. 



Pronotum decidedly longer than broad, moderately narrowed 

 anteriorly. The posterior angles considerably produced back- 

 wards ; a deep (though fine) transverse impression a little 

 behind the middle. 



Thorax with the surface extremely uneven, consisting of 

 large smooth bulbous tubercles. 



Hind body of the male clothed with long fine hairs (very 

 easily rubbed off). The terminal segment forms a large oval 

 plate, concave above, with the lateral margin strongly turned 

 up and abruptly thickened in the middle ; the posterior margin 

 only slightly raised. The ventral plate, forming the under 

 surface of this portion of the hind body, is considerably longer 

 than broad, and is of a somewhat triangular shape, its base
